Measurements of physical quantities are expressed in terms of units, which are standardized values. For example, the LENGTH of a race, which is a physical quantity, can be expressed in units of meters (for SPRINTERS) or kilometers (for DISTANCE runners).EXPLANATION:

The hottest temperatures on Earth are found near the equator. This is because the sun SHINES directly on it for more hours during the YEAR than anywhere else. As you MOVE further away from the equator TOWARDS the poles, less sun is received during the year and the temperature BECOMES colder.

If the BULB glows then the substance is a conductor when the CIRCUIT is closed, and if the bulb does not GLOW even after CLOSING the circuit the object is an insulator.

SpeedAll other physical QUANTITIES, such as force and electric charge, can be expressed as algebraic combinations of LENGTH, mass, TIME, and current (for example, SPEED is length divided by time); these units are called derived units

1 Solar DAY = 86 400 seconds (SI base UNIT). 1 d = 86400 s. ... Hours to Microseconds. A MICROSECOND is exactly 1 X 10-6 seconds.

Semiconductors are substances with properties somewhere between them. ICS(integrated CIRCUITS) and electronic discrete components such as diodes and transistors are made of semiconductors. COMMON elemental semiconductors are SILICON and germanium. Silicon is well-known of these. Silicon forms most of ICs.I hope it helps...

Answer: Salt can be RECOVERED from its solution by 'CRYSTALLISATION'. Crystallisation' is a better technique than 'evaporation' because it REMOVES soluble IMPURITIES also, which do not get REMOVED in the process of evaporation.ww

ᴜᴛɪᴏɴ :-ANGLE between incident ray & mirror = 40°Reflection ray = ?Taking the NORMAL in the middle of the mirror . Now ,the ONE of the angle is 40° and the other angle will be 90° - 40° = 50° . So angle of incidence = 50° . As we know that , angle of incidence = angle of reflection . Hence, reflected angle = 50° . _____________________ ☞ ❷ Sᴏʟᴜᴛɪᴏɴ :-Angle between incident ray and reflected ray = 100°angle of reflection = ?From the above solution , angle of incidence = angle of reflection .So, 2( angle of incidence or reflection ) = 100° ⇒ 2 ( ∠i ) = 100° ⇒ ∠i = 100°/2 ⇒ ∠i = 50° ♦ ∠i = ∠r ⇒ ∠r = 50° _____________________ ☞ ❸ Sᴏʟᴜᴛɪᴏɴ :-Angle of incidence = 20°Angle of reflection = ? ♦ ∠i = ∠r ⇒ ∠r = 20° _____________________ ☞ ❹ Sᴏʟᴜᴛɪᴏɴ :-Angle of incidence = 20°Angle of GLANCE = ?Glancing angle :- Angle between incident ray and mirror is glancing angle ♦ ∠g = 90° - i ⇒ ∠g = 90° - 20° ⇒ ∠g = 70° _____________________ ☞ ❺ Sᴏʟᴜᴛɪᴏɴ :-Angle between incident ray and mirror [ angle of glancing ] = 30°Angle between reflected ray and mirror [ angle of glancing ] = ? ♦ Angle between incident ray and mirror = Angle between reflected ray and mirror ⇒ Angle of glancing = 30°

It is composed MOSTLY of carbon and hydrocarbons, which contain energy that can be RELEASED through combustion (burning). Coal is the largest source of energy for generating ELECTRICITY in the world, and the most abundant fossil fuel in the United States. Fossil fuels are formed from the remains of ANCIENT organisms.

An electrical insulator is a material in which the ELECTRON does not flow freely or the atom of the insulator have tightly bound electrons whose INTERNAL electric charges do not flow freely; very LITTLE electric current will flow through it under the influence of an electric field.

Gravity, ALSO called gravitation, in MECHANICS, the universal force of attraction acting between all matter. ... On Earth all bodies have a weight, or downward force of gravity, PROPORTIONAL to their MASS, which Earth's mass exerts on them. Gravity is measured by the ACCELERATION that it gives to freely falling objects.

Newton's second law states that the acceleration of an OBJECT is DIRECTLY related to the net force and inversely related to its mass. Acceleration of an object depends on TWO THINGS, force and mass.

The motion in which all POINTS of a MOVING body UNIFORMLY along a straight line is called translatory motion. Some of the EXAMPLES for translatory motion are: Man running. Bus moving.Explanation:HOPE IT HELPS.......

A bird's body is not a good conductor of electricity. Birds can sit on power LINES and not get ELECTRIC shocks because the electricity is always looking for a way to get to the ground. The birds are not touching the ground or ANYTHING in CONTACT with the ground, so the electricity will stay in the power linehope it helps dearif found helpful MARK it as brainiliest and follow

Stomata are found in both plants and ANIMALS. Plant stomata are pore structures that regulate GAS exchange of carbon dioxide, OXYGEN and water vapor in and out of a plant. ... Some animal stomata are USED for nutrient or gas intake, LIKE the nostrils or mouth.
